Practical Report on human sexual reproduction.

BIOLOGY 2: PRACTICAL REPORT HUMAN inner REPRODUCTION Re work is the generation of new-sprung(prenominal) psyches of the same(p) species. In a knowledgeable procreation individuals be derived from one invoke and no special generative structures are involved. The simplest prepare is fission, occurring for the most musical composition in unicellular organisms. Simple multicellular organisms, such as sponges and coelenterates, re piss by budding where a new individual arises as an outgrowth (bud) from the parent. In fragmentations, the individual breaks into twain or more parts, each capable of growth to con bodyation a new individual; this is seen in flatworms and algae. Most animals moreover reproduce by a process involving specialized reproductive cells called gametes. They fuse to produce a new individual with a different heritable makeup. This process is known as sexual reproduction. Sexual reproduction involves the fusion of two haploid gametes to form diploid zygo te. The fe young-begetting(prenominal) gamete, oram (unfertilized egg) is a relatively large cell. The male gamete, the spermatozoa is generally a small flagellated cell. It occurs in its simplest form in conjugation. In more complex forms organisms the gametes are produced in special organs such as the carpel and stamen in blossoming plants and the ovary and testes in animals. The immenseness of sexual reproduction in constitution is that it allows genetic interlingual rendition in a population, which is therefore give able to lodge to the changing environment.

Part A : IDENTIFYING THE variety meat OF THE M ALE AND FEMALE procreative SYSTEMS i)The mal! e reproductive administration The process of Meiosis occurs in the organ called the testes. The two testes are located in a at large(p) pouch of scrape up three layers thick; this is because sperm production cannot occur at normal body temperature. The temperature in the scrotum is some 3 degrees down the stairs Celsius. The epididymis serves to store, mature and transport spermatozoa between the formal and...
